+## [1.1.0] - 2026-06-02
+
+### Added
+
+#### Date Checker Tool
+- New "Date Checker" tool page accessible from FAB → Tools menu for tracking item expiration dates
+- Swipe-to-delete with animated removal and staggered enter/exit animations
+- Expired status display with visual indicators
+- Auto-scroll and highlight animation for new entries
+
+#### Tools Page
+- New "Tools" entry in FAB menu linking to a dedicated tools landing page
+- Date Checker as the first tool module
+
+#### Theme & Visual
+- `YaYaTheme` introduced and applied to all Activities for unified theming
+- Legal holiday badges now display with colored background and continuous edge rounded corners
+- Holiday badge wave-scale entrance animation
+- Personal shift badges redesigned with light circle background + centered text
+- Shift badge circular base to avoid overlapping with selection ring
+
+#### Year ↔ Month View Transition
+- BottomCard slide-in animation and fade effect during year/month view transitions
+- Month→year view no longer forces collapse state to expand
+
+#### Performance
+- LunarCache LRU cache for lunar/solar term calculations with startup pre-computation
+- Macrobenchmark module with automated Baseline Profile generation
+- Baseline Profile covering date checker, shift settings, tools page, and core calendar scenarios
+- `ComposeTrace` cross-platform trace markers for Perfetto/Systrace
+- SolarDay static cache to eliminate repeated object creation
+- MiniMonth pure Canvas rendering eliminating 96 Text measurement overhead
+- `graphicsLayer(translationY)` replacing `offset(Dp)` to avoid layout passes
+- Aggregated `CalendarUiState` to reduce Compose recomposition
+- `remember` stabilization for lambdas and computations
+- Scene-based `profile.sh` with `--all` batch mode for 15 automated trace scenarios
+- Perfetto trace analysis script (`analyze-trace.sh`)
+- Trace build type for release + retained trace markers
+
+#### Build & Tooling
+- Spotless 8.5.1 code formatter with ktlint integration
+- `.editorconfig` for ktlint Composable function naming rules
+- Dependency update checker and auto-upgrade tool integration
+- `app_icon` shrunk to 512×512 and converted to WebP (446KB savings)
+- 152 GIF assets batch-converted to animated WebP format
+- `uiTooling` moved to `debugImplementation`; unused `@Preview` and `kotlin-test` entries removed
+- `sketch` library for GIF/WebP display (`sketch-compose` + `sketch-animated-webp`)
+- PowerShell performance tracing script (`profile.ps1`)
+
+#### Documentation
+- Comprehensive `AGENTS.md` at every directory level (root, app, core, scripts, etc.)
+- Updated `DEVELOPMENT.md` with Perfetto trace analysis and emulator launch commands
+- Updated `CLAUDE.md` to reflect pure Android project structure
+
+### Changed
+
+- Project migrated from Kotlin Multiplatform (KMP/CMP) to pure Android (`:app` + `:core`)
+- All Compose UI and business logic consolidated into `:core` module; `:app` remains a thin shell
+- Removed KMP/CMP plugins, iOS app module, and `:shared` module
+- `androidApp` module renamed to `app`
+- Collapse animation refactored: removed fling velocity threshold, now spring-driven
+- `CalendarPager` ↔ `WeekPager` switching uses `AnimatedContent` for smooth crossfade
+- Year view page year calculation uses `settledPage` to prevent flicker during swipe
+- ViewModel decoupled from Compose runtime, migrated to `StateFlow`
+- `LunarCache` made injectable with extracted repeated computations
+- MenuItem and ToolItem unified to use `Card(onClick)` pattern
+- Holiday badge null checks simplified to Elvis operator
+- `@Suppress` annotations cleaned up with deprecated API replacements
+- Removed unnecessary P0 code (custom combine, dead StateFlow, duplicate grid algorithms, runBlocking)
+- Removed debug logging from LicensesScreen and BottomCard
+
+### Fixed
+
+- Lunar first-day month name no longer appends redundant "月" suffix
+- Year view stale year display on enter
+- Year view page year flicker during swipe transitions
+- Collapse animation flicker when switching between CalendarPager and WeekPager
+- Folded state cross-month dates not grayed out in week view
+- Date checker swipe-to-delete state misalignment and deprecation warning
+- Shared element transition animation loss after year view page change
+- Night mode theme transparency issues with explicit background colors
+- Predictive back gesture failure and end-of-animation flash on certain devices
+- Back animation residual transition eliminated with `snapTo`
+- Fast swipe collapse/expand failure, now uses progress threshold detection
+- `graphicsLayer` optimization reverted due to excessive GPU compositing overhead on real devices
+- Reverted shared element transitions in favor of zoom + fade animation
+
+### Removed
+
+- iOS app module (`iosApp/`) and all related Xcode project files
+- `:shared` module and `shared/build.gradle.kts`
+- Shared element transition animations (replaced by zoom + fade)
+- Year/month scroll wheel picker with haptic feedback (reverted)
+- Aliyun Maven mirrors (switched to Maven Central / Google)
+- Unused Compose runtime ProGuard keep rules
+- Temporary performance monitoring logs (trace markers retained)

 # YaYa
 
-基于 Kotlin Multiplatform 与 Compose Multiplatform 的跨平台日历应用,Android 与 iOS 共享同一套 UI 与业务逻辑。
+纯 Android + Jetpack Compose 日历应用，支持农历/节气/节日、个人班次排期，提供月/周/年三种视图。
+
+<div>
+    <img src="app/src/main/assets/app_icon.png" />
+</div>
 
 ## 特性
 
-- **流畅的视图切换** —— 月视图、周视图、年视图三种模式,拖拽手势驱动月↔周折叠,弹簧动画自动吸附
-- **无限滑动分页** —— 基于 `Int.MAX_VALUE` 的虚拟分页,前后无边界翻页
-- **完整中式日历** —— 公历 + 农历 + 二十四节气 + 传统节日,ISO 8601 周起始(周一)
-- **个人排班周期** —— 自定义工作/休息循环,与公共节假日独立
-- **Material 3 设计** —— 动态配色,深色模式

 - `kotlinx-datetime` 处理所有日期逻辑
 - `tyme4kt` 提供农历、节气与传统节日
 - `sketch` 渲染 GIF 动画
-- 双模块:`:shared`(UI + 逻辑) · `:androidApp`(薄壳)
-- iOS 入口为 `MainViewController.kt`,Xcode 工程位于 `iosApp/`

+# 发布流程
+
+## 1. 更新 CHANGELOG.md
+
+按倒序（新版在前）在 `[Unreleased]` 下方添加新版本条目，格式遵循 [Keep a Changelog](https://keepachangelog.com/en/1.1.0/)。
+
+底部添加版本链接：
+
+```
+[x.y.z]: https://github.com/DefectingCat/yayacal/releases/tag/vx.y.z
+```
+
+## 2. 更新版本号
+
+编辑 `gradle.properties`：
+
+- `app.version.base` 改为新版本号（如 `1.2.0`）
+
+编辑 `app/build.gradle.kts`：
+
+- `versionCode` 递增 `+1`
+
+> `app.version.base` 优先于 `build.gradle.kts` 中的默认值，因此以 `gradle.properties` 为准。
+
+## 3. 构建 Release APK
+
+```bash
+./gradlew :app:assembleRelease
+```
+
+产物路径：`app/build/outputs/apk/release/app-release.apk`
+
+## 4. 提交、打 Tag、推送
+
+```bash
+git add CHANGELOG.md gradle.properties app/build.gradle.kts
+git commit -m "release: vx.y.z"
+git tag vx.y.z
+git push origin main --tags
+```
+
+## 5. 创建 GitHub Release
+
+```bash
+gh release create vx.y.z \
+  app/build/outputs/apk/release/app-release.apk \
+  --title "YaYa vx.y.z" \
+  --notes-file CHANGELOG.md
+```
+
+`--notes-file` 会读取 CHANGELOG.md 全文作为 Release body。
